Parker 712230 Steel Flared Tube Plug 7/8 in 37 Degree

Product Description

The PARKER 712230 is a steel flared tube plug designed to cap or seal hydraulic and gas handling lines terminated with a 37-degree flare end. Machined from steel, this plug installs directly into a flared tube end with an outside diameter of 7/8 inches, providing a rated maximum working pressure of 5000 psi. It is used by hydraulic technicians, plumbers, and HVAC mechanics to isolate or blank off active fluid or gas circuits during service, system modification, or pressure testing. The package contains 2 plugs per unit.

This plug is suited for industrial hydraulic systems, pneumatic circuits, and gas handling connections where a 37-degree flare fitting interface is present. Typical applications include capping unused ports on hydraulic manifolds, isolating branch lines during maintenance, and plugging open tube ends during equipment repair or system expansion. It is appropriate for both light-duty and heavy-duty hydraulic fluid service up to the rated working pressure.

Installation Notes

Installation is performed by qualified hydraulic or mechanical technicians. Always depressurize and bleed down the hydraulic or gas circuit completely before removing any fitting or installing this plug. Use appropriate flare fitting wrenches to avoid deforming the flare seat. Follow applicable industry standards and equipment manufacturer guidelines for hydraulic fitting torque and assembly procedures.
